Various types of hydraulic impact hammers, ranging from small and versatile models to heavy-duty offshore impact hammers.
Foundiz offers a wide range of hydraulic impact hammers for a variety of foundation techniques.
Impact hammers, also known as hydraulic impact hammers, are used for driving precast concrete piles, wooden piles, steel pipe piles, sheet piles, and H-sections. A falling weight strikes the pile head, driving the pile to the desired depth in a controlled manner. In most cases, the drop weight is accelerated internally to increase the impact force on the pile head.
Depending on the application, impact hammers are used in combination with a piling rig featuring a fixed or free-suspended leader, or suspended from a crane. In addition, compact solutions are available that can be mounted as an attachment on an excavator.
Are you looking for an impact hammer, pile driving rig, or a complete pile driving machine for your project? Foundiz can help you select the right solution, tailored to the pile type, soil conditions, and project circumstances. This is done based on technical advice and drive ability predictions.
Foundiz supplies various types of impact hammers for applications in foundation techniques. These impact hammers are used to drive various types of piles, including concrete piles, steel pipe piles, sheet piles, and H-beams.
The product line ranges from compact impact hammers for light- and medium-duty applications to heavy-duty hydraulic impact hammers for large-scale and offshore projects, including underwater pile driving applications.
Hydraulic impact hammers are primarily used in situations where vibration is not effective enough, such as in dense or compacted soil layers. In such conditions, impact hammers provide the necessary impact force to drive foundation elements to the required depth.
Foundiz offers a wide range of impact hammers and related equipment for a variety of applications.

Foundiz is an authorized dealer for Dawson Construction Plant and supplies the brand’s full line of hydraulic impact hammers.
Dawson impact hammers are based on practical experience and designed for driving steel pipe piles and sheet piles, among other applications, offering simple operation and a high degree of reliability. They are used in projects that require high impact force and consistent performance.
In soft soil, steel pipes and sheet piles can often be driven to depth using a vibro hammer. However, in compacted soils, the penetration rate of vibro hammers decreases, or vibration is no longer possible. In such cases, hydraulic impact hammers offer the right solution for driving foundation elements to depth in a controlled manner and with sufficient energy.
Dawson impact hammers are available in various models, suitable for light, medium, and heavy-duty applications, including underwater pile driving. In addition, they can be equipped with various accessories, such as pile caps, sleeves, and sheet pile legs, allowing a wide range of steel casings, sheet piles, and H-beams to be efficiently driven to depth.
Foundiz is also a dealer for Movax, a specialist in foundation equipment for use on excavators.
In addition to its well-known sidegrip vibro hammers, Movax also supplies hydraulic impact hammers with drop weights ranging from approximately 1,500 kg to 4,000 kg.
With the help of attachments and accessories, these impact hammers can be easily coupled to excavators, making them versatile for use on projects where mobility and a compact footprint are important.
Hydraulic impact hammers can be used in various ways, depending on the application and project environment.
When used in conjunction with a pile driving rig, a guide ensures precise guidance of the impact hammer and the pile. It is also possible to use free-hanging impact hammers, in which the hammer is positioned on the pile using a crane.
Compact configurations are also available for specific applications, such as attachment systems for excavators with or without attachment booms. These allow for flexible operation, even in confined spaces or at difficult angles.
Impact hammers can be equipped with various accessories, such as pile caps, sleeves, and sheet pile adapters.
These accessories make it possible to drive a wide variety of pile types and profiles, including steel pipes, sheet piles, and H-beams. This makes hydraulic impact hammers suitable for a wide range of foundation projects.
Consulting and Drive Ability Predictions
The choice of the right impact hammer and driving method depends heavily on pile specifications and soil conditions. Foundiz provides support in this area through technical advice and drive ability predictions.
Based on soil data and pile type, we determine which impact hammer and configuration are best suited for the project. The results are documented in a clear and concise report, so that it is clear in advance which approach is the most efficient and feasible.
This reduces the risk of problems during execution and results in a more predictable pile-driving process.
We would be happy to advise you on the right solution for your application and project conditions.
